Orientation is everything, especially when it comes to find the right spot to catch a colectivo in Buenos Aires. If you have made experience with the public transport system, in particular with the buses, you know what I'm talking about. Often it's very hard to figure out which bus to take for a certain destination, and more importantly, to find the right bus stop. If you ever happen to be clueless at the bus terminal on Constitution Plaza, this orientation sign in front of the train station comes to the rescue. All you now need to know is the number of the colectivo line and the direction you are heading. Simple, isn't it?
